Very nice, the rendered demo for all the file types appear to render flawlessly and load instantly on page load, and looking in the DevTools the parsers are split into different Wasm bundles for each file type xslx, docx and pptx:

  docx 458kb raw 217kb gzipped
  pptx 574kb raw 253kb gzipped
  xslx 601kb raw 269kb gzipped

I expected the Wasm bundles to be large and a lot more bigger than that for some reason.

ChatGPT.com can benefit from using this library (or such a library) for rendering a preview of the file in a side panel on the right, instead of just giving me a download link to the outputted/transformed docx/pptx/xslx file.
